RC Pro Controller and DJI RC/ RC 2 with FCC hack by Sincoder

Modifications & Firmware Updates

288

From the message he sent me it will it just needs to be applied twice, once before the update and again after.

289

Let us know how you get on :+1:

@MasterYeti sorry I thought you was referring to my earlier post for the rc pro,
Which is completely different as @SparkyFPV mentioned the other day further up the thread.

So I can confirm that I have updated my DJIRC and reapplied the FCC patch with no issue.

If you choose to do the same just make sure you do the following:

  1. Download the latest version of the software from https://www.dji-fcc.com/djifcc.zip (the version I got from this link had a file modified date of 18/06/23)

  2. Re-apply the patch using the newly downloaded djifcc.exe to your controller on the existing software version (mine was on 01.03.0100)

  3. Open DJI Assistant 2 (Consumer Drones Series) and update the software on the controller to 01.03.0400

  4. Close the DJI Assistant 2 (Consumer Drones Series) and run the djifcc.exe again to apply the patch on the new update.

  5. Enjoy the FCC unlock on the new version :slight_smile:

N.B. The djifcc.exe does not like being run in quick succession and depending how eager you are will give you a popup saying wait a while before you can run it again :slight_smile: This is not just for this version, I had the same thing when I ran it previously. This time can vary, some places on the web say wait 5 minutes, I had to wait 2 hours but it will eventually let you complete the patch again.

I just run it 3 or 4 times and all is well. I have never waited a long period of time.

294

I can confirm the above procedure works exactly as described. There was an anxious couple of hours waiting due to the running too many times in quick succession issue but all good now.

I do wonder if this is the beginning of the end for the hack though. Hopefully sincoder will find a work around for not being able to install from scatch on the latest firmware version

I messaged sincoder last week heā€™s now working on a patch for the RC2

298

Iā€™ve downloaded a copy of the 01.03.0100 firmware for the RC, is there a way to install this back on the device? Canā€™t see any options through DJi Assistant

299

What version are you on now and why do you want to change it?

300

I made the mistake of updating to the 0400 so want to roll it back to try and fix the fcc patch

301

You cant :scream:

This is what DJI does :sob: they increase the Anti-roll back value which means you cant downgrade

This is why we always say donā€™t upgrade

302

Damn, they must have changed something as iā€™m sure in the past iā€™ve seen options to downgrade. Thanks for confirming.

303

They have increased the ARB from 0 on all the other firmware, to a 2 on the latest

The reason and the only reason is to stop the exploit

304

You canā€™t rollback the firmware. DJI has put anti rollback on the 0400 version.

305

well I also got stung by updating before I checked here (lesson learned). why do DJI bother though.

so, any way to defeat the downgrade check?

failing that, is sincoder working on a patch for the new version?

306

Hi @_gl, it looks as though youā€™re quite new here :wave:t2:

Why not nip over to the Introductions page, and say hello properly and tell us a bit about yourself. :+1:t2:

307

nope. example ā€œforce_fcc onā€. thatā€™s all you need.
